Repairing Smith & Wesson 22A Through Ultrasonic Cleaning

Smith & Wesson’s 22A pistol is great for competitive and recreational shooting with its durable design and light weight body of 38.8 oz. Equipped with an adjustable target sight, this pistol has a full length sight bridge with a weaver-style optics mount. It can also be taken apart for cleaning or other purposes with minimal tool use. Regular maintenance checks for both internal and external components of your Smith and Wesson 22A handgun are important to keep it at its best. An ultrasonic cleaner can help you perform thorough cleaning procedures on the inside of your firearm.

How to Clean a Smith & Wesson 22A pistol with an Ultrasonic Gun Cleaner

If you own or service Smith & Wesson 22A pistol or similar handguns you will definitely appreciate how an ultrasonic gun cleaner can save time and effort when it comes to cleaning and maintaining the weapon. An ultrasonic weapons cleaner is fast, thorough and safe because unlike some solvent washers and aerosol sprays, today’s ultrasonic gun cleaning solution is biodegradable, minimizing disposal problems with spent solutions.

Here you will learn:

  • How an Ultrasonic Gun Cleaner Works
  • How to Select and Set Up your Ultrasonic Weapon Cleaner
  • How to Disassemble, Clean and Reassemble your Smith & Wesson 22A firearm

How an Ultrasonic Gun Cleaner Works

Ultrasonic cleaners are used in a wide range of applications to remove virtually any soil or contamination with the power of cavitation action. Cavitation action describes the implosion of billions of minute bubbles in the ultrasonic cleaning solution as they contact all components of your Smith & Wesson 22A hand gun. The bubbles are created by generator-powered ultrasonic transducers bonded to an ultrasonic cleaning tank and typically operate at an ultrasonic frequency of 37 to 42 kHz (37,000 to 42,000 cycles per second).

The imploding bubbles quickly and safely remove grease, powder residues and other contaminants that could interfere with reliable operation of your Smith & Wesson 22A hand gun. So tiny are the bubbles that they penetrate minute cracks, crevices and blind holes impossible to reach with conventional hand gun cleaning tools. The ultrasonic weapons cleaner will complete the job in less than 15 minutes. Meanwhile you can attend to other activities.

How to Select and Set Up your Ultrasonic Handgun Cleaner

A bench or table-top ultrasonic cleaner such as the LR617 along with its lubricating pan is ideal for sporting goods shops, servicing departments and the serious hand gun collector cleaning one or two handguns at a time. Whatever the model and size ultrasonic handgun cleaner you use there are steps to take before you start the cleaning operation by following the manufacturer’s operating instructions.

  1. Fill the ultrasonic weapons cleaner tank to the fill line (or approximately 2/3 full) with water and an ultrasonic cleaning concentrate diluted per manufacturer’s instructions. We recommend CLN-LR215 diluted 1 part to 10 parts of water.
  2. In the same way, fill the auxiliary lubricating pan with an ultrasonic gun lubricating solution and place it into the ultrasonic cleaner tank. Ready-to-use CLN-LR212 is a good choice. Make certain that the bottom of the lubricating pan is in contact with the cleaning solution.
  3. Turn on the ultrasonic cleaner and operate the unit for about 30 minutes to drive off cavitation inhibiting entrained air in both the cleaning solution and the lubricating solution. Degassing is complete when bubbles stop coming to the surface. Note that this step must be performed every time you use fresh cleaning or lubricating solutions.

How to Disassemble, Clean and Reassemble Your Smith & Wesson 22A Pistol

Step 1: Disassembling the Smith & Wesson 22A Firearm

To begin dismantling, first perform a safety check on your firearm. Remove the magazine making sure it is empty. Do not point your firearm at anyone to avoid casualties. Always perform this procedure before cleaning.

Pull the slide backwards to double check the insides of your S & W 22A pistol. Keep it in a pulled back position to remove the front part of the top cover. Press the button underneath the slide near the trigger guard. Make sure that you have a proper grip on your firearm when pressing on the button. You may opt to wrap a finger or two around the trigger guard to hold components in place as you take them apart.

Press on the button and grab the front part of your slide. As you press on the button for the second time, lift the part until it is completely loosened from the base. Set it aside to focus on the other half of the slide.

To remove the pulled back portion of the slide, hold down the spring inside with your finger. Doing so will prevent the spring from flying out. As you keep the spring down, slowly release the slide from its locked position. It should come off easily together with the recoil spring and guide rod. Now concentrate on the lower assembly to completely take apart your firearm.

Carefully remove the two screws on each side of the hand grip to free the middle metal assembly. Pull down the handgrip to reveal the frame of your Smith & Wesson 22A Pistol.

Safety Tip! Give utmost care in the disassembly of your firearm since it is composed of several small screws and springs. Arrange them in such a way that would help you return them to their proper places.

Voila! Your Smith & Wesson 22A hand gun has been successfully disassembled. Its parts are now ready to be cleaned using an ultrasonic cleaner.

Step 2: Cleaning the Smith & Wesson 22A Firearm

Use the weapons kit brushes and tools to remove powder residues, bullet shavings, carbon and other loose contaminants. Tip: If the weapon is extremely dirty it should be cleaned using hot water to prepare the cleaning bath.

Put the hammer in the cocked position. Lift the star shell ejector and place a spacer between the star and cylinder to enhance cleaning action. Position your weapon parts in the mesh basket in a way to avoid air entrapment. Lower the basket into the cleaning solution and set the timer for 7-10 minutes. Cleaning time depends on the condition of the weapon.

At the end of the cycle remove the handgun components from the bath. If they are not clean replace them in the bath until the cleaning is complete. Do not reach into an operating ultrasonic bath. Remove the basket from the bath if you want to inspect or rearrange the parts.

After cleaning rinse the parts in fresh water to remove all traces of the cleaning solution, shake them to remove excess water and allow them to drain. Compressed air will aid in this process.

Return the weapon parts to the basket.

Next place the lubricating pan into the ultrasonic cleaner again making certain that the bottom of the lubricating pan is in contact with the ultrasonic cleaning solution. Put the basket into the lubricating solution and set the timer for 10 minutes. Ultrasonic waves will pass from the ultrasonic cleaning bath to the lubricating bath and thoroughly lubricate the weapon parts.

After the lubricating step remove the parts and allow them to drain. Do not blow dry. Inspect then oil the parts according to the manufacturer’s instructions before reassembly.

Step 3: Reassembling the Smith & Wesson 22A Pistol

Begin putting your pistol back together by fitting the middle metal piece in the hand grip. Attach these together using the four screws that were removed earlier. Then reposition the recoil spring and guide rod assembly inside the shorter part of the slide. Pull back and lock the slide to put the barrel back on the firearm.

Once the spring assembly is secured inside, fit the barrel in its original place on top of the middle metal piece. Move the piece back and forth a couple of times to make sure that it is properly attached. Leave it pulled back once you are certain that it is placed as it should be. Return the longer end of the slide on top of the middle metal frame. The longer part should be slightly forward and away from its other half. You may now release the pulled back barrel to fit the slide.

Finally, insert the magazine in your firearm and it’s good to go.

Congratulations! You have just reassembled your “brand new” Smith & Wesson 22A Pistol.

Additional Weapon Cleaning Tips

Oils that rise to the surface of the bath should be skimmed off and disposed of properly. When the ultrasonic handgun cleaner solution becomes discolored or cleaning takes longer it is time to replace it. Drain the tank and dispose of the spent solution according to local regulations. Take the time to remove sludge that settled to the bottom of the tank then clean the tank.
